I'm having a problem in CF 2016 with a grid I'm trying to populate with a bound cfc method. If my method returns no data, I get a JavaScript error: ext-all.js:18 Uncaught TypeError: Cannot read property 'id' of undefined(…). However, this code executes fine in CF 9.
Is this a bug? Or should I be doing something different in CF 2016 to handle a method that returns no data?
My exact version is 2016.0.0.298074.
Below is the code I'm testing with. First, the page with the cfgrid:
<cfajaximport tags="cfform,cfpod,cfdiv,cfgrid" />
<h1>Invoke method</h1>
<cfinvoke component="data" method="getColors" returnvariable="qColors">
<cfdump var="#qColors#" label="invoked method">
<h1>Bind method</h1>
<cfform id="frmColors">
<cfgrid name="grdColors" format="html" pagesize="5"
bind="cfc:data.getColorsRemote({cfgridpage},{cfgridpagesize},{cfgridsortcolumn},{cfgridsortdirection})">
<cfgridcolumn name="COLOR" header="Color" width="300">
<cfgridcolumn name="ALT" header="Spanish" width="300">
</cfgrid>
</cfform>
And this is the component: data.cfc
<cfcomponent output="false" displayname="data">
<cffunction name="getColors" access="public" returntype="query" output="false">
<cfset var q = 0>
<cfset qColors = getDataSet()>
<cfquery dbtype="query" name="q">
SELECT COLOR, ALT FROM qColors
ORDER BY COLOR ASC
</cfquery>
<cfreturn q>
</cffunction>
<cffunction name="getColorsRemote" access="remote" returntype="struct" output="false">
<cfargument name="page" type="numeric" required="true">
<cfargument name="pageSize" type="numeric" required="true">
<cfargument name="gridSortColumn" type="string" required="false" default="">
<cfargument name="gridSortDir" type="string" required="false" default="">
<cfparam name="arguments.gridSortColumn" default="COLOR">
<cfparam name="arguments.gridSortDirection" default="ASC">
<cfset var q = 0>
<cfset qColors = getDataSet()>
<cfquery dbtype="query" name="q">
SELECT COLOR, ALT FROM qColors
<cfif arguments.gridSortColumn NEQ "" AND arguments.gridSortDir NEQ "">
ORDER BY #arguments.gridSortColumn# #arguments.gridSortDir#
</cfif>
</cfquery>
<cfreturn queryConvertForGrid(q, arguments.page, arguments.pageSize)>
</cffunction>
<cffunction name="getDataSet" access="private" returntype="query" output="false">
<!--- create dataset --->
<cfset qColors = queryNew("COLOR, ALT","VarChar, VarChar")>
<!--- comment out this section to simulate no data --->
<cfset newRow = queryAddRow(qColors, 7)>
<cfset temp = querySetCell(qColors, "COLOR", "Red", 1)>

<cfset temp = querySetCell(qColors, "COLOR", "Indigo", 6)>
<cfset temp = querySetCell(qColors, "ALT", "Indigo", 6)>
<cfset temp = querySetCell(qColors, "COLOR", "Violet", 7)>
<cfset temp = querySetCell(qColors, "ALT", "Violeta", 7)>
<!--- end comment --->
<cfreturn qColors>

</cfcomponent>
